3 Claims.

This invention relates to a pump construction particularly adaptable to and for the pumpage of gasoline and other liquids to be dispensed.

There are various types of so-called pedestal pumps for the dispensing of gasoline and motor fuels which are arranged to have mounted therein the pump mechanism. The pump mechanism maybe manually or power operable. When .10.. power operable, the pump is usually electric motor driven.

One object of the present invention is to construct the pump assembly so that it'may be universally adapted for mounting in and upon various types of pedestal pumps and other supports.

A second object of the invention is to combine in'one pump assembly provision for motor driving the pump and for manually operatingthe same.

Another object of the invention is to so arrange the pump assembly whereby the respective parts thereof may be readily detached one from the other for removal of parts requiring replacement, repair or adjustment. I

Anotherobject of the invention is to provide a filter or screen construction for a pump which, in addition to automatically separating water, dirt and other matter from the liquid being pumped, collectsthe filtrate and which when the filter or screen is removed, simultaneously removes the separated filtrate from the pumping system.

The chief feature of the invention consists in the construction of the various parts and the association thereof, whereby the foregoing objects are accomplished.

Another feature of the invention consists in the belt tensioning construction which can be readily manipulated without belt removal.

The full nature of the invention will be understood from the accompanying drawingsand the following description and claims:.

In the drawings, Fig. 1 is a side elevation of a motor driven pump assembly embodying the invention, the assembly being arranged for side wall mounting.

Fig. 2 is an end elevation thereof. a

Fig. 3 is a view similar to Figure 2 but on a smaller scale and of a modified type of support and mounting. g i

Fig. 4 is a side elevation of'a modified form of construction illustrating the manual pump operation, parts being shown in central section for illustrating the same and other parts in detail. This figure illustrates the central section, the pump rotor and housing;

Fig. 5 is a transverse sectional view through the:

pumpassembly' discharge mechanism and illus' trates in detail the screen and .filter' andrelief valve constructions and mounting. V p

Fig. 6 is an end elevational view of a modified form of mounting, the driving mechanismbeing omittedij r I In Figs. 1 and 2 of the drawings, 10 indicatesa relief valve and filter and screen housing vwhich includes atone side the anchoring orfsupporting bracket portion 11 whereby through bolts, nuts or the like, inserted in the openings 12, thepump' assembly maybe suitably mounted and supported; The housing 10 includes a plurality of upwardly directed bosses 13 adapted to det'achably support by means 14 a motor unit,rindicated generally by the numeral v15, the shaft 16 of which 'mountsia V-shaped driving pulley 17. The lower face of the housing 10 is adapted to abuttingly support a rotor housing 19 which is arrangedgesee Fig. 4-jto provide a pump or rotorlchamber"20 ,therein, having an open face 21.and an aligned bearing portion 22. Mountedin mechsmb r is a-pump rotor, indicated generally by the numeral '23, and the same is mounted upon the shaft24 rotatably supported at oneend in bearing portion 22of rotor housing 19.. I The rotor chamber20 is closed by a.cover or cap 25 secured to the same as at 26, and saidcover or cap terminates in an extended bearing I27 ar,- rangedto receive a sealing construction, indicated generally by the numeral 28,, and retained in operative relation by the cap 29. This sealing construction is illustrated, describedand claimed in a co-pending prior application. v

The elongated bearing supports the rotor shaft 24 and seals the pump. The extended end of said shaft terminates in'"a shoulder 30 against'which abuts the hub'31. threadedas at 32. The hub is retained upon the shaftby the nut 33 and is prevented from rotat-' ing thereon by the key constructionB, or any other equivalent structure. Projecting radially from the hub 31 are the spiderarms 35 that, sup-v port a rim 36, said rim including an inwardly tapered face frusto conicalin form, as at 37. Each of the spider arms 35 is provided with an aperture 38 and said apertures are equidistant from the axis and are of like size. I

Threadedly mounted on the hub 31 is a. supplementary hub 39 from which radiallyextehds a plurality of spider arms 40 that terminate in a peripheral rim 41 inwardly and frusto comically tapered as at 42. J I I The resultant construction is a V-pulley, the

- b r is separated from the liquid that has been supnot 71 th't efiective diameter of which is: obtained by axial adjustment of the two pulley forming plates. To maintain the plates in predetermined spaced relation, one of the arms 40 includes a threaded aperture 43 that receives a locking plug in the form of a threaded bolt 44, terminating in a pin 45 thatis receivable by any one of the openings 38 in the arms 35. The adjustable pulley construction, as shown clearly in Fig. l, is arranged for belt alignment with respect to the driving pulley 17 on the motor and when the belt 46 suit: ably connects the same with the desiredtension in the belt, the motor will properly drive the rotor 23 for pumpage of the liquid supplied to the housing 10 by the intake pipe indicated by the dotted lines in Fig. 1 and by the humeral '47;

Pipe 47 communicates with the intake 48 in chamber 49 in the housing 10. Ghamber 49 com municates with chamber 50 through an apertured partition 51 having the aperture 52 therein; A well 53 communicates with portion 54--see Fig. l -'ol the pumprotori housing 19 and the pump discharge from the rotor lio'usii'lg communicates with th'ihlet 55 of charnber 56, Having the 1's; charge 5'7 to which the discharge pipe or conduit or the unit is connected. Chamber 56 has an opening 58 therein supports a relief valve structureindicated generally by the numeralt The relief valve discharges into chamber '60 that free with the chamber 50.

[If the pressur in: beyond that for which 'th e relief valv is game excess liquid is bypassed into chamber sag-and iififii ea'iateiy is ecirculated by the pump without passing through the screen ing to the chamber 49-. In other-words, the lidgar 84 that meshes with the pinion 80. hub 82 includes the aligned radial notches 85 uid only passes once through the screen even though recirculated.

Whenever manual operation is desired or required, the belt 46, if a motor is provided with the structure, is removed and there is threadedly mounted upon threaded hub 31 --see Fig. 4 a pinion 80. As shown clearly in Figs. 4 and 5, the closure or cap '76 is extended as at 81 and the same is adapted to receive a hub 82 suitably secured as at 83 thereto. Said hub includes a plate The adapted 'to seat the pin 86 carried by portion 87 of the crank having the handle 88. The locking end '89 is receivable by the recess 90 in the itiiisioh -81 of the cap or closure 76. Rotation of the hand crank, therefore, will rotate the rotor shaft 24 and manual operation is thus obtained.

' In Fig. 3 a different type of support from that shown. in Figs. 1 and 2 is illustratedand herein tli supporting'structure includes a pair of spaced, side members Bland 'detach'ably supported were between, as t 92, is a plate 93. said late is suitably apertures and the bolts 14 shown Figs. 1 and 2 not only secure thefnotor to the housing 10, butalso securing the housing 10 to the transverse member 93.

, In Fig, 6 a modified form of suppo t is, nns trate'd wherein the housing 110 includes lateral faces to which are detacha blyv secured as at 112 upon opposite sides, the outwardly arreste supporting flanges 111. These in turn ares'uitabl'y supported upon adjacent sides of ap'air of sup-1 ports. w The resulting construction, therefore, one that is' universa1ly adaptable for various types of mountings and which is universally adapt able for operation in that it maybe poweropei' ablefor manually operable. Furthermore, it will L15 be feadilyapparnt that the relief. vaiv strut}: ture and the filter or screen may bev readily re} moved without detaching any of' t e assembled parts other than the closuresjah'd that the rotor or the motor may be detached from the nousihg 1o for repair or replacement.
